This change failed to correctly set the pf_pdesc for ICMP-in-ICMP lookups, resulting in ICMP error packets potentially being dropped incorrectly. Specially, it copied the ICMP header into a separate variable, not into the pf_pdesc. Populate the required pf_pdesc fields for the embedded ICMP packet's state lookup.
